1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 25JUL23 0000Z, SUPER TYPHOON 05W (DOKSURI) WAS LOCATED NEAR 
17.7N 124.6E, APPROXIMATELY 279 NM NORTHEAST OF MANILA, PHILIPPINES, AND 
HAD TRACKED NORTHWESTWARD AT 08 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 130 KNOTS GUSTING TO 160 
KNOTS. SEE REF A (WTPN31 PGTW 250300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 91W) PREVIOUSLY LOCATED NEAR 
5.9N 143.3E IS NOW LOCATED NEAR 8.0N 141.4E, APPROXIMATELY 211 NM EAST-
SOUTHEAST OF YAP. ANIMATED MULTISPECTRAL SATELLITE IMAGERY REVEALS A 
BROAD, ILL-DEFINED LOW-LEVEL CIRCULATION (LLC) PARTIALLY OBSCURED BY 
BROAD FLARING CONVECTION ALONG THE WESTERN AND SOUTHERN PERIPHERIES. A 
250035Z ASCAT-C BULLSEYE PASS REVEALS A WEAK BROAD CIRCULATION WITH A 
SWATH OF 25-30 KNOT WINDS OFFSET TO THE SOUTHERN SEMICIRCLE. 
ENVIRONMENTAL CONDITIONS ARE MARGINAL CHARACTERIZED BY MODERATE (20KT) 
VERTICAL WIND SHEAR DUE TO NORTHERLY FLOW FROM STY 05W. SEA SURFACE 
TEMPERATURES REMAIN CONDUCIVE AT A WARM 29-30C. GLOBAL MODELS ARE IN 
STRONG AGREEMENT THAT 91W WILL STEADILY CONSOLIDATE AS IT TRACKS 
GENERALLY NORTH-NORTHWESTWARD OVER THE NEXT 24-48 HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS 
REMAINS LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
